Excerpt from Oxy-Acetylene Welding Practice: A Practical Presentation of the Modern Processes of Welding, Cutting, and Lead Burning, With Special Attention to Welding Technique for Steel, Cast Iron, Aluminum, Copper and Brass Welding Field. The welding process is undoubtedly one of the greatest contributors to the efficient and economical manufacture of the modern automobile. It has made possible higher standards of body design and may be given almost exclusive credit for the light weight and great strength of the present-day motor car, producing stronger and better working parts through the use of pressed steel instead of the heavy castings or riveted parts, such as axle housings, Fig. 1, and manifolds, tanks, bodies, etc., Fig. 2. In the field of automobile repair it is rapidly assuming an equally important place, affording a quick and inexpensive means Of perma nent repair to parts no longer obtainable from the supply house or manufacturer and permitting the building up of weak parts or the altering of the chassis, as may be required. This great adaptability of the welding unit has made it an essential part of the equipment of every efficiently managed repair shop.
